Question

what is the area of the shaded area (BLUe area)

Answer 1

Answer:

area of big circle=πr²

=3.14×(5)²=78.5 cm²

area of small circle=πr²

=3.14×(3)²=28.26 cm²

area of shaded part=area of big circle-area of small circle

=78.5-28.26=50.24cm²

therefore your answer is 50.24cm²

Answer 2

Answer:

Hii,

Step-by-step explanation:

$\huge\underline{\underline{\sf\pink{ANSWER:-}}}$

At first, we have to find the area of the outer circle by using the formula (πr²) , Where r = 5cm.

Therefore , πr²

=22/7 × 5²

= 22/7 × 25

= 78.57 cm²

Then, we have to find the area of the inner circle by using the same formula where r = 3 cm

πr² = 22/7 × 3²

= 22/7 × 9

= 28.28 cm²

Therefore, the area of the blue or shaded part = ( area of outer circle - area of the inner circle )

= ( 78.57 - 28.28 ) cm²

= 50.29 cm²

Therefore the area of the shaded part or the blue part is 50.29 cm²

Hope it will help you...
